I believe this is Practitioner, but the only advert I can find is a one for 1942 which has a different movement (10AX). the dial and case looks the same. But the movement is a 17 J 10AE which according to the movement info on the db is a 1940 movement. I haven't received the watch as yet and the picture of the movement is not clear enough to make out any date mark.

But the case is marked Bulova with a shield after the name. plus serial number 8712886 under that its marked 10K gold filled

Ok gents, I'm going to be a little silly with the pictures here, but we just don't see the complete package like this from the 1930's very often.

I believe this is the 1939 Buckingham, with original bracelet, outter box, and display case. It also comes with the Bulova Guarentee Bond as well as an extra link for said original bracelet and an ORIGNAL cardboard display cutout! Woooooow...

The only difference I see is this is possibly missin the center seconds hand shown in the advertisement.

Here's an interesting newer Bulova Pocket Watch, dated N0, or 1970, but with the movt dated N1. The movt itself is a 17j 16AC, which is the venerable Unitas and later ETA 6497. It has shock protection, and is an excellent example of a modern quality movt in a pocket watch. The same ebauche was used by Panerai until recently, and you will find it in large size wristwatches by various manufacturers.
